Originally, I was expecting some sort of virtual art gallery. Well, that's really what it is actually. The "game" features various artworks from the Japanese artist Kuniyoshi Kaneko, who illustrated the Japanese release of Alice in Wonderland. The game serves as an interactive gallery, featuring the artist's works largely themed around Alice in Wonderland, as well as many nudes, and possibly erotic artworks (I'm not really sure what the context is for some of them.) The game also features a few rare disturbing images and attempts at being scary, so be warned. At some point, I discovered a card hidden in something, with a clue written on it. The clue led me to another card and so forth. At some point I discovered a door that had a combination lock on it. I spent quite a while searching for cards containing hints for opening it. There is an ending to this game. Honestly, this was way more entertaining then I ever expected it to be. Also a bit terrifying. I recommend taking screenshots of the cards if you want to see it through. Some cards appeared to be red herrings. Good luck.
